R. Scott Bakker has blogged about the ongoing lack of reviews or sales for Disciple of the Dog and about the impact of the economy on his status as an author. In particular, he states that whilst his books are selling and remain in print, he may need to take up a day job in the near future, which will reduce the amount of time he has to write. After some panicked comments, he put up a second blog post confirming that The Second Apocalypse series will be completed, but that after he finishes The Unholy Consult (the third book in the Aspect-Emperor sub-series) it will no longer be viable for him to remain a full-time author (presumably barring a massive jump in his book sales), so the timeframe for the remaining books will become much less certain.
This is disconcerting news, especially after Bakker pledged to complete the entire series in another five years or so. However, this news presumably puts that possibility in doubt.
Another timely reminder that no author, despite their critical acclaim and even their sales success, is immune from the current harsh, economic climate.
